close........................ :) It seemed like it was quieter if I pushed a rag around the #5 (third one back on the passenger side) injector. So I removed the injector and could see it had a washer, but there was combustion leakage past it, and a bit of fuel residue on the valve cover around the injector hole. So i swapped the washer for one of the LBZ ones and just fired it back, perfect, no leakage.

Thanks guys, really appreciate the help. It's got to where I rarely post tech questions on the "other " board, Pat and crew have this one going so well.
